Mt Fitzroy: Missing 250 Pages of Earthcore?

At the end-of-podcast Q&A session for Earthcore, you talked about ~250 pages being cut from the original story. Obviously a lot of that was action and plot that ultimately could be (and was) done without, but I wonder if there was also some character development or other backstory that we might see in the sequel. Could the FDO give us a hint or maybe a teaser for any of what we missed that might show up later?
